Gives you ideas you never thought you wanted....

Because of this book, flumphs have just become a critical part of one of my campaigns. That's how seriously it turns the critters around, people.

It takes some of the most loathed monsters in the history of the game, and it makes them into creatures that are awesome, if not necessarily 100% serious (flail snails remain a little on the silly side - that said, they're intelligently on the silly side.) And Dire Corbies have become downright scary, in a Descent kinda way.
